Directions

  1. Preheat the oven to 375 degrees F (190 degrees C).
  2. Bring a large pot of lightly salted water to a boil. Add the vegetables, and cook uncovered for 3 minutes. Drain in a colander, then immediately immerse in ice water for several minutes until cold to stop the cooking process. Once the vegetables are cold, drain well, and set aside.
  3. Cook garlic and butter in a large skillet over medium heat until garlic starts sizzling, about 3 minutes.
  4. Stir in chicken broth, heavy cream, thyme, nutmeg, and cayenne pepper; cook until mixture begins to simmer, about 5 minutes.
  5. Coat a 9x13-inch baking dish with olive oil and spread vegetables evenly over the oil.
  6. Pour broth and cream mixture over vegetables and top with half of the grated Parmigiano-Reggiano cheese.
  7. Cover baking dish loosely with aluminum foil, place on a baking sheet, and bake in the preheated oven for 40 minutes.
  8. Remove baking dish from the oven and top with remaining Parmigiano-Reggiano. Bake uncovered until vegetables are browned, bubbling, and tender, about an additional 30 minutes.
  9. Remove from the oven and let rest for 20 minutes.

This was an epic fail. Thank goodness it was just the two of us and did not have company for dinner. I read the recipe, watched the video and re-read the recipe. In my mind, I was questioning the amount of broth that the recipe calls for. Indeed, I was correct. After having baked for a total 80 minutes and then rested for 20 minutes the vegetables were sitting in a pool of milky liquid. I had to scoop out some of the vegetables, drain the liquid, make a roux and thicken the liquid. Still, the flavor of the dish was lacking. Because the vegetables were not seasoned while cooking there was just no way to season them properly. 1 - 1/4 cups cream, NO broth, add onion and season the vegetables after blanching in the salted water would fix this. But that would be a different recipe, wouldn't it?

This is really good!! I followed the recipe except I didn't have any parmigiano-reggiano cheese so I used 3/4 cup marble cheese. I am not a big fan of thyme so I only put in a pinch. I will definately make this again!!! Alot better than just plain old boiled turnip!

Good way to sneak in the root veggies. Followed the recipe with a little extra added cheese, but felt it lacked a little kick, despite the cayenne. Thinking I might add some jalapeno next time.
